：在郊区的矮林管理，如除草和垃圾清理，每年进行的网站，并在网站，已被遗弃了很短的时间（自1995年以来）或很长一段时间（自1975年以来）使用陷阱陷阱调查地面甲虫动物。科、种和个体的数量在被遗弃很长一段时间的地点最大。在各种立地条件下，松蚜科的个体率最高，且长期废弃的立地高于管理的立地。优势种龟纹瓢虫的数量与弃耕年限呈正相关。蚜虫、白蛉的个体数与凋落物量和EC呈正相关。总个体数与土壤硬度和含水量呈负相关，个体数与相对光子通量密度和土壤温度呈负相关。因此，地面甲虫的反应与废弃年的地板环境的变化似乎不同的昆虫群体。除趋势对应分析表明，治理地和短期弃耕地的甲虫群落结构相似，但与长期弃耕地的甲虫群落结构不同。特殊的物种组的地面甲虫的记录，以放弃的年数。因此，为了保护甲虫的多样性，利用不同地面管理的森林进行镶嵌林是可取的。
: Ground beetle fauna were investigated using pitfall traps at sites in a suburban coppice forest where management, such as weeding and litter cleaning, was conducted every year, and at sites that had been abandoned for a short time (since 1995) or for a long time (since 1975). The numbers of families, species, and indi- viduals were greatest at a site that had been abandoned for a long time. The rate of Silphidae individuals was highest at each kind of site, and was higher at a site abandoned for a long time than at managed sites. The num- ber of Eusilpha japonica , a dominant species, positively correlated with the number of years abandoned. There were positive correlations between the number of Silphidae and Curculionidae individuals, and litter amount and EC. Negative correlations existed between the total number of individuals and soil hardness and water content, and between the number of Nitidulidae individuals and relative photon flux density and soil temperature. Therefore, the reactions of ground beetles to changes of floor environment with abandoned years seemed to differ for each insect group. Detrended correspondence analysis revealed that the community struc- tures of ground beetles at managed sites and at a site abandoned for a short time were similar, but differed from that at a site abandoned for a long time. Peculiar species groups of ground beetles were recorded in order of the number of years abandoned. Consequently, to conserve the diversity of ground beetles, mosaic foresta-tion using forests of various floor managements is desirable.
